Description

具低旋鎖阻力之螺絲Screw with low twist lock resistance

本創作係有關於一種螺絲的設計，特別是指一種具低旋鎖阻力之螺絲。This creation is related to the design of a screw, especially a screw with low twisting resistance.

參閱圖1所示，習知螺絲1包含有一桿體11，一設於該桿體11一端之螺頭12，複數螺旋環設於該桿體11上之螺牙13，以及複數形成於該桿體11且設於任二螺牙13間之切肋14，且該每一切肋14之自由端與該等螺牙13相連接，同時任二螺牙13間形成一排屑空間15；故，該螺絲1於使用時，首先於該螺頭12施予一旋鎖扭力，以使該等螺牙13受帶動而旋切物件（圖中未示），此時利用該等切肋14協助該等螺牙13破壞該物件之纖維，以達該螺絲1的鎖合定位效果。Referring to FIG. 1, the conventional screw 1 includes a rod body 11, a screw head 12 provided at one end of the rod body 11, a plurality of spiral threads 13 formed on the rod body 11, and a plurality of threads formed on the rod body 11 The body 11 is provided on the cutting rib 14 between any two threads 13, and the free end of each rib 14 is connected with the threads 13, and at the same time a chip row space 15 is formed between any two threads 13; therefore, When the screw 1 is in use, a twisting torque is first applied to the screw head 12 so that the threads 13 are driven to cut objects (not shown in the figure). At this time, the cutting ribs 14 are used to assist the Wait for the thread 13 to damage the fiber of the object to achieve the locking and positioning effect of the screw 1.

然，實際使用後發現，該螺絲1雖可利用該等螺牙13與該等切肋14進行切削；惟，鑒於該等螺牙13呈完全牙設置，致使該等螺牙13於旋鎖進入該物件內的過程中，其所承受的旋鎖阻力相對較大，更是容易造成該等螺牙13過度磨損、鈍化之情事產生，此外，鑒於該等切肋14之自由端係與該等螺牙13相連接，致使該等螺牙13間所形成之排屑空間15受到該等切肋14阻斷，當該等螺牙13逐漸旋鎖入該物件時，該等切肋14不僅無法協助切削產生之切屑外，更會阻擾該等切屑的排出，致使該等切屑容易先積存於該等切肋14一側，必須等待該等切屑累積至一定程度後，才能受到擠壓而越過該等切肋14並向外排出，更是導致過量的切屑積存於該等螺牙13間，且該等切屑無法順利沿著該等排屑空間15向外排出，因此，不僅造成該螺絲1的旋鎖扭力與阻力增加，以及造成鎖合效率降低且影響後續鎖合作業的進行外，若是該螺絲1持續擠壓積存之切屑更可能造成該物件裂材之情事產生，實有待改善。However, after actual use, it was found that although the screw 1 can use the threads 13 and the cutting ribs 14 for cutting; however, since the threads 13 are completely arranged, the threads 13 are inserted into the screw lock During the process inside the object, the twist-lock resistance it bears is relatively large, and it is more likely to cause excessive wear and dullness of the threads 13; in addition, since the free ends of the cutting ribs 14 are connected to the The threads 13 are connected, so that the chip removal space 15 formed between the threads 13 is blocked by the cutting ribs 14. When the threads 13 are gradually screwed into the object, the cutting ribs 14 cannot In addition to the chips generated by assisting cutting, it will also hinder the discharge of the chips, causing them to accumulate on the side of the cutting ribs 14 first, and they must wait for the chips to accumulate to a certain level before they can be squeezed and passed. The cutting ribs 14 are discharged outwards, which causes excessive cutting chips to accumulate between the threads 13, and the cutting chips cannot be discharged smoothly along the chip discharge spaces 15, thus not only causing the screw 1 In addition to the increased torque and resistance of the screw lock, and the reduction in the efficiency of the locking and affecting the subsequent lock cooperation, if the screw 1 continues to squeeze the accumulated chips, it is more likely to cause the object to crack, which needs to be improved.

再者，該等切肋14之設計雖期望能針對纏繞之切屑予以切削，惟，其效果不如預期亦如前所述，同時又鑒於該等切肋14之自由端與該等螺牙13相接，更是導致該等排屑空間15受到壓縮，造成該等排屑空間15所能容納的切屑受限，更是導致該螺絲1的鎖合定位效果不佳，同時降低該螺絲1可承受之拔脫作用力，實有待改善之必要。Furthermore, although the design of the cutting ribs 14 is expected to be able to cut the entangled chips, its effect is not as expected and as described above, and at the same time, considering that the free ends of the cutting ribs 14 are relative to the threads 13 Connection, it also causes the chip removal spaces 15 to be compressed, which limits the amount of chips that the chip removal spaces 15 can accommodate, and even causes the screw 1 to have a poor locking and positioning effect, and at the same time reduces the screw 1’s ability to withstand The pull-off force really needs to be improved.

因此，本新型之目的是在提供一種具低旋鎖阻力之螺絲，其有助於加速排屑，供足夠切屑容納，以及提供輔助切削作用，更加減少鎖合時的旋鎖阻力與扭力，以達提升鎖合速度與鎖合定位效果。Therefore, the purpose of the present invention is to provide a screw with low twist-lock resistance, which helps to accelerate chip removal, provides sufficient chip accommodation, and provides auxiliary cutting action, and further reduces the twist-lock resistance and torque during locking. It can improve the locking speed and locking positioning effect.

於是，本新型具低旋鎖阻力之螺絲包含有一桿體，一設於該桿體一端之螺頭，以及複數螺旋環設於該桿體上之螺牙；其中，該每一螺牙具有二分別由該桿體向外傾斜延伸之牙面，一形成於該等牙面相接處之牙尖，以及複數間隔設於該等螺牙上之輔助單元，而該每一輔助單元具有一由該牙尖向內凹設之容置槽，以及至少一形成於任一牙面上且緊鄰該容置槽之凸塊，且該每一凸塊之自由端未與該桿體相接，以使該等螺牙間所形成之排屑空間不受該等凸塊阻斷；故，鎖合時，藉由該等凸塊將該等螺牙旋切之旋切孔略為頂撐，更有利於後續螺牙在低阻力的狀況下快速進入物件，以達提升鑽切與擴孔效果，同時該等凸塊有助於破壞物件之纖維與產生之切屑，藉以避免該桿體受纏繞，此外，該等切屑得以順利地向外排出，且不會受到該等凸塊阻擾，再配合該等容置槽與該等排屑空間供足夠切屑容置，更是降低鎖合時的旋鎖扭力與阻力，增加該螺絲所能承受之拔脫作用力，以及有效提升鎖合速度與鎖合定位效果。Therefore, the screw with low twist-locking resistance of the present invention includes a rod body, a screw head arranged at one end of the rod body, and a plurality of spiral threads arranged on the rod body; wherein each thread has two A tooth surface extending obliquely outward from the rod body, a tooth tip formed at the junction of the tooth surfaces, and a plurality of auxiliary units spaced apart on the screws, and each auxiliary unit has a The accommodating groove recessed inwardly of the tooth tip, and at least one protrusion formed on any tooth surface and adjacent to the accommodating groove, and the free end of each protrusion is not in contact with the rod body, so that The chip removal space formed between the screws is not blocked by the protrusions; therefore, when locking, the rotary cut holes of the screw teeth are slightly supported by the protrusions, which is more advantageous In the follow-up, the screw thread quickly enters the object under the condition of low resistance to improve the drilling and reaming effect. At the same time, the bumps help to destroy the fiber and the generated chips of the object, so as to prevent the rod from being entangled. , The chips can be smoothly discharged outwards without being disturbed by the bumps, and the accommodating grooves and the chip removal space are matched to provide enough chips to accommodate, which reduces the screw lock during locking. Torque and resistance increase the pull-out force that the screw can withstand, and effectively improve the locking speed and locking positioning effect.

In this embodiment, the protrusions 3332 are arranged in plural, and each protrusion 3332 is arranged in a diamond shape. In addition, each accommodating groove 3331 may be provided with a protrusion 3332 at one end, as shown in FIG. 3 or 4, or each accommodating groove 3331 may be provided with a protrusion at both ends Blocks 3332, and the protrusions 3332 are respectively provided on different tooth surfaces 331, as shown in FIG. 5 and FIG. 6, and the following takes FIG. 3 as an example for description.

參閱圖2、圖3及圖7，該螺絲3鎖合時，首先於該螺頭32施予一旋轉扭力，以使該等螺牙33於一物件4表面鑽切出一旋切孔（圖中未示），而該等螺牙33逐漸旋入該物件4的過程中，鑒於該等螺牙33之牙尖332上凹設有該等容置槽3331，使得該等螺牙33呈非完全牙型態設置，進而大幅降低該等螺牙33於旋切時所承受之旋鎖阻力，以及避免該等螺牙33發生過度磨損、鈍化之情事，接著配合該等凸塊3332輔助該等螺牙33將該旋切孔略為撐開，以便後續螺牙33在低阻力的狀況下快速進入該物件4內，進而提升鑽切與擴孔效果，而後在該旋轉扭力的持續帶動下，該等凸塊3332得以針對該物件4之纖維與產生之切屑進行頂推與切削，並有效破壞該物件4之纖維與切屑，以使經切削後的切屑與纖維不會纏繞於該桿體31，此外，該等排屑空間34不受該等凸塊3332所阻斷，因此，鎖合過程中所產生之切屑得以藉由該等容置槽3331與該等排屑空間34順利且快速地向外排出，而不會受到該等凸塊3332阻礙或是積存於該等凸塊3332處，更是加快該等切屑排出之速度，以及提升排屑之順暢性，再者，該等凸塊3332的設置不會壓縮該等排屑空間34，故，該等排屑空間34得以供足夠切屑所容納，再加上該等容置槽3331亦可供該等切屑容納，更可使得該螺絲3穩固鎖合定位於該物件4內，進而有效提升鎖合速度，降低鎖合時的旋鎖扭力與阻力，增加該螺絲3所能承受之拔脫作用力，以及提升鎖合定位效果。Referring to Figure 2, Figure 3 and Figure 7, when the screw 3 is locked, a rotating torque is first applied to the screw head 32, so that the screws 33 are drilled to cut a rotary hole on the surface of an object 4 (Fig. Not shown), and the screws 33 are gradually screwed into the object 4, as the cusps 332 of the screws 33 are recessed with the accommodating grooves 3331, the screws 33 are not The complete tooth profile is set, thereby greatly reducing the twisting resistance of the screws 33 during rotary cutting, and avoiding excessive wear and dullness of the screws 33, and then cooperate with the protrusions 3332 to assist the The thread 33 slightly expands the rotary cut hole, so that the subsequent thread 33 can quickly enter the object 4 under a low resistance condition, thereby improving the effect of drilling and reaming.
